Accrington 3-0 Dag and Red
Accrington substitute Padraig Amond hit a brace as Dagenham were consigned to an eighth straight league defeat.
The Daggers went close through Michael Spillane's header and Abu Ogogo's fierce strike which Luke Joyce did well to clear off the line.
Stanley assumed full control after the break and led when Craig Lindfield fired home from Micah Evans's cross.
Amond headed home from a Charlie Barnett centre and swept home from 10 yards to secure the points.
